Simple and reliable way in sternum wound coverage--tripedicle pectoralis major musculocutaneous flap.

Objective: Sternotomy wound infection requires radically debridements and need secondary reconstruction of the resulting defect. Pectoralis major muscular or musculocutaneous flap is quite common in sternal wound closure. We modified the pectoralis major musculocutaneous flap

Design: bipedicle advancement cutaneous flap combined with thoracoacromial myocutaneous perforators, as a "tripedicle" fashion. We tried to utilize the cutaneous pedicle to provide a reliable skin coverage and decrease the wound dehiscence rate in lower one third sternal wound.

Methods: Four patients undergoing median sternotomy surgery between 2004 and 2007 suffered from sternal wound infection and received tri-pedicle pectoralis major musculocutaneous flaps transfer.

Results: No skin paddle necrosis or wound dehiscence occurred in the postoperative course. Cosmetically and chest stability were satisfactory without complains about the daily activity.

Conclusions: Tripedicle pectoralis major musculocutaneous flap is a simple and reliable technique to cover sternal wound defect necessitating resurfacing surgery. The blood supply to the skin paddle can be enriched by the superior and inferior cutaneous pedicle and the wound dehiscence rate is decreased with this technique.
